LIMBING
Limbing a fallen tree is much the same as bucking.
Never stand on the tree that you are limbing. When
limbing, caution is the word. Be careful of the tip
touching other limbs. Always use both hands.
Don't cut with the saw overhead or aligned vertical-
ly with your body. If the saw should kickback, you
may not have enough control to prevent possible
injury.
BUCKING
Bucking is the sawing of a log or fallen tree into smaller
pieces. There are a few basic rules which apply to all
bucking operations. Keep both hands on the handles
at all times. Support logs if possible. When cutting on a
slope or hillside, always stand uphill.
Keep in mind that the wood is heavy and that it will bend
and pinch the saw if improperly supported. The trunk
will weaken at the point where you make the cut unless
the tree is lying on perfectly flat ground or supported as
shown. If you make the cut with the tree on the ground,
don't let the saw's chain dig into the earth; it is harmful
for the saw, and you stand a good chance of being struck
by flying debris.
To cut the trunk, use the bucking and two-cut sequence
shown. The first cut should be no deeper than one-third
the trunk diameter.
